Abstract (en)
[origin: WO2016022884A1] The present invention relates generally to multimode optical fibers (MMFs) and methods for optimizing said MMFs for transmission for at least two optical wavelengths. In an embodiment, the present invention is a multimode optical fiber optimized for multi-wavelength transmission in communication systems utilizing VCSEL transceivers, where the MMF has a bandwidth designed to maximize and equalize channel reach for multiple wavelengths, and/or where the MMF minimizes for wavelength dependent optical power penalties at one or more wavelengths. The alpha coefficient of the refractive index profile is numerically optimized for all wavelengths based on a transmission model that includes calculation of, inter alia, modal dispersion and chromatic dispersion effects.
